Claims

At least one non-electric drug infusion device detachably connected to at least one medical syringe, the device being adapted to infuse a drug from the syringe, the syringe having a liquid delivery port and A cylinder having an open end opposite the fluid delivery port; an elongate plunger assembly having a distal piston opposite the proximal end; and the piston adapted to slide in a sealed manner within the cylinder A drug infusion device comprising:
A body including resistance adding means;
A force member having an arm, and
The arm has a free end close to the resistance applying means,
The force body is configured to be detachably connectable to the proximal end portion of the syringe at a predetermined position spaced from the free end portion of the arm.
A clamp is attached to the infusion device body, the clamp having a long inner wall whose diameter is substantially similar to the diameter of the cylinder of the syringe, and one of the syringes between the opposing ends. Having a long side opening large enough to snap-enclose the part, thereby preventing rotation or movement of the syringe perpendicular to the long axis of the syringe, the syringe Has a ledge adjacent to an open end where the diameter of the cylinder increases, and the clamp is moved by the plunger assembly of the syringe with the force or the user's finger, and the clamp is ledged on the syringe. When snapped onto the cylinder in contact with the cylinder, it contacts one or more sides of the ledge and moves the syringe along its long axis. Those that are made as to hold the odd,
Drug infusion device.

The system of claim 1 , wherein the infusion device is reusable and the drug syringe is disposable.

2. The infusion device according to claim 1 , wherein the resistance applying means has a vacuum chamber, and the vacuum chamber has a sealed slidable piston that forms a wall of the vacuum chamber, and the free arm of the arm.
